Heroes I quit midway through season 3. I actually liked season 1 a lot, despite the sort of frustrating format you mentioned. It had an effective buildup, a sense of wonder and suspense and the finale delivered on promise. Season 2 was just kind of boring nothingness partly due to the strike. But season 3 just kind of wandered around aimlessly in circles. My problem with the Lithgow season was that I felt like if Dexter was as skilled a killer in season 4 as he was in the first three at any point in the season, the sequence of events at the end would have never happened. I hate it when they have to dumb the characters to contrive the story they want.
